In 2007, the City Council adopted an ordinance that allows fees to be collected from property owners to fund the stormwater program. Fees are used for programs including: stormwater drainage capital improvement projects, maintenance of the storm drainage collector system, reduction in flooding occurrences, reduction of pollutants carried by stormwater to our waterways, and fulfilling the City’s Federal and State stormwater discharge permit requirements. In order to be most equitable, a flat fee is imposed on residential units while commercial businesses will be assessed fees based on impervious surface areas (driveways, parking lots, rooftops, etc.) of each developed property.
The City also belongs to the Keep It Clean Partnership a regional stormwater program.
Storm water fees are charged on two separate classes of utility accounts: single-family detached residential and all others. The single-family detached residential have a monthly base rate. The all others classes will be charged a fee that is determined by dividing the calculated total square footage of impervious area on the property by the runoff area unit (RAU) of 3,500 square feet, then multiplying the result by the single-family residential base rate. See 2018 Utility Rates.

The City of Louisville cares about protecting our environment and waterways and is also committed to preserving, enhancing and improving the water quality in Coal Creek. In 2002, the City signed an Intergovernmental Agreement (IGA) with the Watershed Approach to Stream Health (WASH) Project which was formed to combine resources and implement programs to help improve the stormwater quality entering our streams and lakes as a result of runoff from residential, commercial and industrial areas. The city also used this team approach to address and comply with the requirements as mandated by the Environmental Protection Agency (EPA) and the Colorado Department of Public Health and Environment (CDPHE) Phase II Stormwater regulations.
